An optical disk is a medium used for data storage and an optical drive is what’s used to read these disks and also to write on them. The Blue ray disk is very much different from a normal DVD and consists of a ferromagnetic material that is sealed with a plastic coating. There are various types of optical disk drives in the market but the most recent one’s to have captured the consumer electronic market are the Blue ray drives.
A single-layer Blue ray disk can store around 25GB and a dual-layer disk can store 50GB. This storage space is way higher than a normal DVD. Blue ray drives are needed to read and write data on to a Blue ray disk.
Blue ray drives work in a very different way than other disks that we all know. The Blue ray drives actually have a laser inside that helps the reading and writing of data more understandable for the computer. During the whole disk reading process, a laser beam is projected on the disk. This reflects a light. The light changes according to the different effects of the magneto-optical Kerr.
The BDA, also known as the Blue ray Disk Association consist of some of the well known consumer electronic giants. According to them almost all Blue ray drives should be capable of reading the traditional type of DVD’s and CD’s. This is known as backward compatibility.
Although many consumers still use the standard DVD’s and CD’s to watch movies and listen to songs, the Blue ray disk format has gained more popularity over time. Blue ray disks come with more storage space and higher quality than a normal DVD, making it more useful for people who want to get a cinematic experience right at their home.
In the early days where the Blue ray technology was at its initial stage, a few manufacturers used to make products that had Blue ray DVD players and Blue ray drives which could play only DVD’s and not CD’s. But today, the new advancements have changed the Blue ray drives making it possible for the backward compatibility.
Having a high storage space compared to other disks is one of the biggest advantages the Blue ray disk has. Due to the increase of sales, manufacturers of desktop computers and laptops have incorporated Blue ray drives into them. Many computer systems are shipped with the Blue ray drives installed in them. The Sony Playstation-3 was one of the first to use the Blue ray technology.
For manufacturers of traditional DVD’s and CD’s, the Blue ray disk has come up as a major competitor, enveloping most of its customers. After all who would want a DVD with low storage space when a Blue ray disk can be purchased with higher storage space and more features?
